The are lots in Hull - Ella street already mentioned, the ones on Hawthorn Ave (Chalk Lane) demolished (didn't actually know about these)
From what I can tell all the 1920s/30s are a similar design - and usually carry a plaque on one of the houses in the row.
I'm fairly certain they are mentioned in "North Eastern Railway Architecture" by Bill Fawcett (North Eastern Railway Association) - though not in as much detail as he goes into train sheds and stations There are 3 volume - probably v.3 is the right one - will check in the local library next time I pass..
I'll list some more - theses are just in west Hull and the list might not be complete:
Snuff Mill Lane, Cottingham Bungalows

Southwood Ave. Cottingham - more bungalows - practically a mini housing estate

Alliance Ave. (nr. the H&BR bridge) Hull short terrace
http://goo.gl/maps/uArJ4
Ella St. (nr. H&BR docks branch), short 'semi-semi' terraces , already mentioned

There's also a modern estate on "Rainhill Rd." (1980s I think - retired people) - again next to former H&BR docks branch

They're as common as muck!
My knowledge only really extends to West Hull - I wouldn't be surprised if there were more in East Hull. Someone has already mentioned some which were demolished on Hawthorn Ave I didn't know about, and I don't know if any were lost to bombing. They are clearly better than the general victorian/edwardian terraces which as so common in Hull, so I would expect most to survive.
I'd expect the situation to be similar in other NER towns - the Oxford encyclopaedia of British Railway History states that by the 1920s the NER had 4600 staff dwellings!
One obvious one is Faverdale Estate, Darlington, where the NER practically built the town for the wagon works - 200 houses built in the 1920s. I'd guess there are more in York too.
